The present disclosure relates generally to the field of nicotine delivery. The disclosure teaches a nicotine meta-salicylate. More specifically, the disclosure teaches a condensation nicotine aerosol where nicotine meta-salicylate is vaporized. This disclosure relates to aerosol nicotine delivery devices. The delivery devices can be activated by actuation mechanisms to vaporize thin films comprising a nicotine meta-salicylate. More particularly, this disclosure relates to thin films of nicotine salt with meta salicylic acid for the treatment of nicotine craving and for effecting smoking cessation.

The present invention generally relates to thawing a cryogenically frozen sample. The systems, devices, and methods may be used to heat a sample holder, the sample holder configured to receive a sample container holding the frozen sample. A sample thaw start time may be identified by measuring a temperature of the sample container and/or a temperature of the sample. A sample thaw end time may be calculated as a function of the sample thaw start time. In some embodiments, the same thaw start time may be identified by a significant change in a first derivative of a warming curve of recorded temperature measurements. The sample end time may be calculated by adding a constant to the sample thaw start time. The constant may be the average sample thaw time per the sample container.

A method of purifying herbal extract(s) from an herbaceous plant composition includes heating the herbal extracts-containing composition to volatilize at least one of herbal extract(s) into a vapor and condensing the vapor on a substrate or wet extracting the herbal extract(s) by treatment of the herbaceous plant composition or a derivative thereof with a solvent for the herbal extract(s), separating the solution of herbal extract(s), forming a concentrate and casting the concentrate on the substrate to form a coating of the herbal extract(s) on the substrate. A corresponding delivery cartridge and delivery system can include a controllable heating element and the substrate coated with at least one of herbal extract(s). These are configured to allow passage of air over the substrate to volatilize or entrain the herbal extract(s) as a vapor, gas or aerosol for administration to a user.

The invention relates to a method for the repeated activation of orthodontic correction devices with a known critical temperature (Tkrit) and a glass transition temperature (Tg) lying above the critical temperature. In the method according to the invention, in order to guarantee gentle repeated activation, an orthodontic correction device is heated to a temperature that lies above the critical temperature but below the known glass transition temperature. The invention also relates to a device for performing the method.

A control circuitry (11) comprises an adjustable capacitor (C1), and a bias source (111) configured to apply a bias voltage (V2) to said adjustable capacitor (C1) to adjust a capacitance value of the adjustable capacitor (C1). Such a control circuitry may for example be part of a sealing device (1) to seal a medical tubing (2), the sealing device (1) comprising a receptacle (100) to receive said medical tubing (2), the receptacle (100) comprising an electrode arrangement for causing a heat action on the tubing (2).

The disclosure provides an apparatus, system and method of providing a flexible heater on at least one conformable substrate of a medical fluid bag. The disclosed embodiments may include providing a matched function ink set, printed onto at least one substantially planar face of the at least one substrate to form at least: at least one conductive layer capable of receiving current flow from at least one power source; at least one resistive layer electrically associated with the at least one conductive layer and comprising a plurality of heating elements capable of generating heat upon receipt of the current flow; and at least one dielectric layer capable of at least partially insulating the at least one resistive layer.

A respiratory conduit apparatus that conducts a breathable gas for respiratory therapy may include electrical circuit components to assist with therapy. In an example, a delivery conduit for connection with a patient interface and a respiratory therapy device may include a cuff having a microcontroller unit. The cuff may be configured with circuit components for accessory identification, gas characteristic detection for therapy control, heating and communications. In some versions, the delivery conduit may include a controller in a circuit board assembly located at an end of the delivery conduit. The printed circuit board may be configured to control and power the components of the cuff, as well as communicate with a respiratory therapy device.

A steam therapy assembly includes a housing that has an intake and an exhaust to pass air through the intake and the exhaust. A water tank is removably attachable to the housing and the water tank has a fluid port to pass water therethrough for filling the water tank with water. An oil cartridge contains oil and the oil cartridge is removably insertable into the housing. A vaporizing unit is integrated into the housing and the vaporizing unit is in fluid communication between the intake and the exhaust to urge air into the intake and outwardly through the exhaust when the vaporizing unit is turned on. The vaporizing unit vaporizes the water in the water tank into a steam. Additionally, the vaporizing unit vaporizes the oil in the oil cartridge thereby mixing the vaporized oil with the vaporized water.

The present invention generally relates to a heating apparatus, method of using and making the same that can be used to heat a thermoformable prosthetic socket.

A battery-powered scope warmer includes a heated cavity to receive the distal end of a surgical viewing instrument such as an endoscope or laparoscope. The distal end of the surgical viewing instrument is inserted into the cavity in the housing through one or more flexible flaps in the upper portion of the housing. A heating pad forms a curved tray that receives the distal end of the instrument. The flaps enable the distal end of the surgical viewing instrument to be inserted into, or removed from, the cavity in the housing through one or more slits. A de-fogging sponge in the cavity may be moistened with a de-fogging fluid, and one or more absorbent pads may be disposed on the upper portion of the housing for removing excess fluid from the tip of the surgical viewing instrument. The entire warmer, including the batteries, may be disposable.
